Title: Improvements in or relating to contact current changers for polyphase currents
IPC: H02M1/26
Filed: 1944-07-31
Abstract: 587,040. Converting. LA COUR, J. L., and WIDAKOWICH, M. July 31, 1944, No. 14589. Convention date, July 17, 1943. [Class 38 (ii)] A current changer for converting polyphase alternating current 'into direct current,' or vice versa, or into alternating current of another type, comprises a number of bridgeconnected current changer groups which are mutually displaced in phase so that a voltage in one phase of one group is followed by a phase voltage in the next group, all the groups being parallel connected on the direct current side and each group being provided with a current-blocking element common to all the phases and connected in the direct current circuit. The current-blocking elements may consist of choke coils or valves such as dry rectifiers. Fig. 1 shows two three-phase systems differing in phase by 30‹, comprising two transformers T1, T2 having their primaries a1, d1 star and delta connected and joined in parallel. The secondary windings a2, d2 are both delta connected and joined to contacts K1 ... K12 in the direct current circuit. The contacts are actuated by a synchronous motor and locked so that two contacts in the same group cannot be closed simultaneously but overlapping occurs between the closing periods of the contacts of one group and those following in the second group. The resultant direct current has twelve ripples in each period of the original alternating current. If the number of commutating elements is equal to the number of separate current changer groups the closing periods within each group must not overlap but if the commuting elements outnumber the groups then two adjacent phases in the same group as well as two phases in consecutive' groups overlap one another. Instead of providing each current changer group with a transformer a single transformer may be used having one primary winding and two secondary windings star and delta connected. Alternatively, as shown in Fig. 5, each secondary winding may comprise a delta connected part having an extension h. Fig. 6 shows a further modification in which both secondaries are star wound the phase displacement in the two groups being produced by an alternating current generator G placed in the direct Current circuit between the groups. Any number of phases may be used with a corresponding number of current changer groups the secondary voltages of the groups being mutually displaced in phase by 180‹/m,n where n is the phase number and m is the number of separate current changer groups.

Abstract: 1460405 Separators for lead-acid batteries KANEBO Ltd and MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 9 April 1975 [11 April 1974] 14627/75 Heading H1B [Also in Division D1] A microporous separator for a lead-acid battery comprises a fibrous structure of organic polymer fibres which is impregnated with 3% to 30% by weight, based on the weight of the fibrous structure before impregnation, of an organo-polysiloxane and is then cured. The fibres may be natural fibres such as cellulose or wool or synthetic polymer fibres such as phenol formaldehyde resin, polyester, polyamide, polyacrylonitrile or mixtures thereof. The organopolysiloxane may be silicone oil, silicone rubber or silicone varnish, such as methyl hydrogen polysiloxane, dimethylpolysiloxane and phenylmethylpolysiloxane. In one example phenol formaldehyde fibres were cured in a heated bath containing hydrochloric acid and an aqueous formaldehyde solution. The fibres were then dispersed in an aqueous solution containing a surface active agent and made into a sheet by a sheet making machine. An aqueous solution of resol resin was sprayed on the sheet which was then dried and impregnated with an aqueous emulsion of a mixture of the organopolysiloxane, a cross-linking agent and a catalyst. After drying, the sheet was heated at 180 C. for one minute. In organic fibres such as glass fibres and/or a binder or filler such as silica or diatomaceous earth may be included in the fibrous structure.

Abstract: 1,204,407. Cold separation of gas mixtures. McDONNELL DOUGLAS CORP. 27 March, 1968 [28 March, 1967], No. 14700/68. Heading F4P. In a two component gas mixture, e.g. air separation process utilizing at least two fractionating columns 37, 38, Fig. 2, in mutual heat exchange relation, heat is continuously added to the lower part of column 38 below the feed oxygen-rich air inlet 50 and is continuously withdrawn from the upper part of the column by overhead nitrogen having been withdrawn from column 37, a portion thereof compressed at 42 passed through an axially extending coil 62, thereby effecting differential distillation in column 38. The head of column 38 is further cooled by liquid oxygen withdrawn therefrom through a line 68, sub-cooled in a coil 70, expanded at a valve 74 and passed through a coil 78 after which the so-warmed oxygen together with gaseous nitrogen leaving coil 62 and effluent nitrogen from column 38 passes through exchanger 72, 30; product oxygen being compressed at 100. The nitrogen compressor 42 is driven by a turbine 92 which is itself driven by the remainder of the overhead nitrogen from column 37. Additional cooling of column 38 below the feed inlet 50 is provided by an external refrigerant, e.g. helium traversing a coil 66. In a modification, Fig. 4 (not shown), the upper coil 62 is dispensed with and the cold expanded nitrogen is fed directly into the column head. In a further modification for the separation of oxygen, nitrogen and argon the latter is separated in a column 134, Fig. 6, in thermal contact with the lower end of a main column 132 having its mid-portion in thermal contact with an initial column 130 to which feed air is fed at 129, overhead nitrogen withdrawn at 136, and oxygen-rid liquid withdrawn at 142 and expanded into column 132 as feed. Overhead nitrogen from column 130 having been compressed at 138 passes up an axial coil 158 in the base of column 134 to heat the same and also to heat the base of column 132 by transmission of heat therebetween. The so-cooled nitrogen is sub-cooled at 164 and a first portion is expanded at a valve 185 into the head of column 132, a second portion of the sub-cooled nitrogen is expanded at 187 into column 130, whilst a third portion is expanded at 178 into a coil 174 of crude argon condenser 170 having a product argon gas outlet 224. Pure liquid oxygen withdrawn from column 134 through a line 204 is sub-cooled at 206 and is expanded in valves 208, 208<SP>1</SP>, 208<SP>11</SP> into a vaporizing coil 210 which extends within both columns 130, 232 to cool them, after which pure oxygen vapour is discharged as product through a heat exchanger coil 214 and a compressor 222.

Nozzle (54) is carried in a cap (52), and is screwed into a tooth paste type tube (56) containing glue, cement, sealing compound, grease etc.  A double acting air cylinder (K) feeds, canister (51), carrying tube (56), and a shaft (62) driven by an air motor (M) through gears (65), (66) rotates the canister.  Air is supplied through a bore (63) in the shaft to canister (51) for squeezing tube (56).  A nozzle wiping device for cleaning the nozzle after each component has been cemented comprises two shafts (73), each of which has a pinion (74), and a reel (75), Fig. 3 (not shown), and also an L-shaped arm (76).  A tape (77) extends across the front of the nozzle and is connected to the reels. Toothed racks (79) co-operate with pinions (74) so that when nozzle (54) is advanced to the work, the racks rotate the reels to lower the arms (76), and tape (77), clear of the nozzle but when the nozzle is retracted the arms and tape are raised to wipe the nozzle.  A ratchet (81) is provided to allow a clean part of the tape to be presented for each wiping action.  In operation, air is supplied to canister (51) motors (M) and (N) and cylinder (K).  Canister (51) is rotated by motor (M), advanced by cylinder (K), reciprocated by lever (18) to apply cement with a dabbing action, and components (44) and (7) are rotated.
